Description
Technical Field
The utility model relates to the technical field of mill accessories, in particular to a composite cover plate of a discharge end of an autogenous mill.
Background
Mineral processing plants generally employ a crushing and grinding process, with a mill being one of the most commonly used equipment in the process. In recent years, the design and manufacture of mills have been rapidly advanced, and the size has tended to be large. The large semi-autogenous mill and the autogenous mill are popularized and applied in various concentrating mills. Because the large semi-autogenous mill barrel diameter is big, and the granularity of giving ore and grinding steel ball are all bigger, and its welt receives the impact bigger, and the wearing and tearing are very violent, cause welt life short, overhaul change time long, not only wasted a large amount of manpower, material resources, and equipment operation rate is low. Meanwhile, the large-scale semi-autogenous mill generally adopts an alloy cast steel discharge end cover plate, and the following defects generally exist: 1. low hardness, poor wear resistance and short service life; 2. the heavy cover plate has the advantages that the heavy cover plate is heavy, the single piece is more than 1-2 tons, manufacturing defects are easy to occur, and the heavy cover plate has great potential safety hazards in installation, disassembly and transportation; 3. the semi-autogenous mill has low filling rate, and causes severe local abrasion of the cover plate and leads to overall failure.
Disclosure of Invention
The utility model aims to provide a composite cover plate for a discharge end of an autogenous mill, which has the characteristics of convenient replacement and lower use cost.
The technical scheme adopted by the utility model is as follows: the composite cover plate at the discharge end of the self-grinding machine comprises a bottom plate and lifting bars,
the base plate comprises a base plate base body made of rubber materials, a wear-resistant plate made of metal materials is compounded on the upper surface of the base plate base body, a strip-shaped clamping groove is formed in the upper surface of the base plate base body, and fixing bolt passing holes and matching bolt passing holes which are all transparent up and down are formed in the region of the base plate base body, where the clamping groove is located;
the lifting strip comprises a lifting base body which is also made of rubber materials, a wear-resistant strip made of metal materials is compounded on one side surface of the lifting base body, and a matching groove with a T-shaped section is formed in the lower side surface of the lifting base body;
and
the lower part of the lifting matrix is clamped in the corresponding clamping groove;
the fixing bolts penetrate through the holes from top to bottom;
after the square heads of the square head bolts are clamped in the corresponding matching grooves, the square heads of the square head bolts pass through the matching bolt passing holes from top to bottom.
The section of the lifting matrix is trapezoid.
The utility model has the advantages that: the replacement is more convenient, and the use cost is lower. The composite cover plate at the discharge end of the self-grinding machine is fixed on the ore pulp lifter of the self-grinding machine through bolts, and is convenient to replace. The whole rubber is taken as a matrix, so that the weight is lighter, and the replacement is convenient. The wear-resistant plate or the wear-resistant strip prepared by adopting metal at the special part improves the wear resistance of the part easy to wear, avoids the condition that the cover plate needs to be replaced integrally due to partial wear, and reduces the use cost.

The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
FIG. 1 is a perspective view of the bottom plate of a composite cover plate at the discharge end of an autogenous mill in accordance with an embodiment of the utility model;
FIG. 2 is a perspective view of a lifter bar of a composite cover plate at the discharge end of an autogenous mill in accordance with an embodiment of the utility model;
fig. 3 is a front cross-sectional view of a composite cover plate at the discharge end of an autogenous mill in accordance with an embodiment of the utility model in use.
In the figure:
10. the base plate, 11, the base plate matrix, 12, the wear-resisting plate, 13, the clamping groove, 14, the fixing bolt through hole, 15 and the matching bolt through hole;
20. lifting bars, 21, lifting matrixes, 22, wear-resisting bars, 23 and matching grooves;
30. a fixing bolt;
40. square head bolts 41, square heads 42 and nuts.
Detailed Description
Examples, see fig. 1-3: the compound apron of autogenous mill discharge end includes bottom plate 10 and lifting bar 20.
Further speaking:
the soleplate 10 comprises a soleplate base 11 made of rubber material. The wear-resistant plate 12 made of metal material is compositely fixed on the upper surface of the base plate 11 by means of adhesion and the like. The upper surface of the base plate 11 is provided with a strip-shaped clamping groove 13. Obviously, the extending direction of the card slot 13 is generally along the longitudinal direction of the base plate body 11. The base plate 11 is provided with fixing bolt passing holes 14 and matching bolt passing holes 15 which are all penetrated up and down in the area where the clamping groove 13 is positioned.
The lifting bar 20 comprises a lifting base 21, also made of rubber material. A wear strip 22 made of a metal material is compositely fixed to one side surface of the lifting base 21 by adhesion or the like. Obviously, the wear strip 22 must be located on one side of the lifter bar 20 that is impacted during operation. The lower side surface of the lifting base 21 is provided with a matching groove 23 with a T-shaped section.
More specifically:
the lower portion of the lifting base 21 is caught in the corresponding catching groove 13.
The fixing bolt passing hole 14 is internally provided with a fixing bolt 30 from top to bottom. When in use, the bottom plate substrate 11 is fixed on the ore pulp lifter of the mill through the fixing bolts 30, and the ore pulp lifter is provided with bolt holes for screwing the fixing bolts 30 in advance.
After the square heads 41 of the square head bolts 40 are caught in the corresponding fitting grooves 23, the corresponding fitting bolt passing holes 15 are passed through from top to bottom. That is, when in use, the square head 41 of the square head bolt 40 is clamped in the matching groove 23, so that the square head bolt 40 cannot rotate and cannot be separated, the pulp lifter is also provided with a through hole for the bolt body of the square head bolt 40 to pass through, and then the lifting bar 20 can be fixed on the pulp lifter through the nut 42 matched with the square head bolt 40.
Optimizing:
the cross section of the lifting base 21 is trapezoidal.
Therefore, by adopting a split design and taking rubber as a matrix, the wear-resisting plate and the wear-resisting strip which are prepared by metal materials are matched at key parts, the difficulty of installation and replacement is reduced, and the comprehensive use cost is lower.
The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structures or equivalent processes using the descriptions and drawings of the present utility model or directly or indirectly applied to other related technical fields are included in the scope of the utility model.
